Z '0 all-whom it may concern:

Be it known that I, FRANKLIN KNIGHT KENNEDY, Jr, lieut., Ordnance Dept.U. S. A.., a citizen of the United States,stati0ned at.

ficers or employees in prosecution of work for the G-overnmenh'or anyother person in the United States, Without payment to me of any royaltythereon. 1 o

The subject of this invention is a'target frame upon which the usualtarget may be mounted. 1 v p In target shooting it is customary to haveattendants or markers 'stationed'behind' the protecting butts whose dutyit is to lower the target, mark the location of theshotand again raisethe target. 'At present it is usual to have two attendants assignedto'thi s duty oreach target. j

The present lnvention aims toprovide a target frame whlch 1ssemi-automatic mac-i tion and which may be handled by one attendant withease and facility.

I WVith these and other objects in view the invention resides the novelarrangement and combination of parts and in details of constructionhereinafter described' and claimed, it being understood that changes inthe precise embo'dimentof the invention; herein disclosed may bemadewithin the scope of what is claimed without departing from the spirit ofthe invention.

One practical embodiment of theiinvention is illustrated intheaccompanying drawings, wherein:

Fig. 1 is a view in front elevation of a target frame constructedinaccordance with my invention; 7

Fig. 2 1s a plan view of the frame with the carriage in place therein,the Lip-rights of the frame shown in section;

Fig. 3 is a view in vertical longitudinal.

section of the treadle boX or pit.

Referring to the drawings by numerals of reference In carrying out myinvention I provide uprights 10, preferably formed of channel iron,which may be secured in place upon a suitable base by the foot brackets11. Diagonal braces 12 have ends secured to the uprights 10 and thelrupper ends secured to collars 13, which encircle a rod or shaft 1tbridging the space between the uprights and having its ends supported inclamps 15 se cured to the uprights. Mounted for rotation upon the shaft14; is a sprocket wheel 16 which is held against longitudinal. move'ment upon the shaft by the collars 13.

Mounted for vertical reciprocation in the uprights is a carriagecomprising upper and lower "longitudinal bars 17 suitably connected asby. riveting to the end bars 18, which bars are preferably made ofchannel lIOZL' For the'purpose of strengthening the carriage braces 19may be: connected to the upper and lower longitudinal bars Secured tothe upper bars 17 adjacent each end thereof is a stirrup 2'0, andsecured to the lower bars 17 adjacent each end thereof and m verticalalignment. with the stirrupi20 is a stirrup 2lforined with: an inturnedunderlying plate 22. The stirrupsQOand 21- are adapted to receivethestandards 23 of the target 24: the inturned plate '22 serving'to preventthe. standards falling through the st1rrups. i Mounted on each end bar18'of the carriage is a pair of rollers 25 "adaptedzto engage the front:or rear flange tof theupright lOand between such pair 'o f.roller s isalso mounted a roller 26 adapted toengage-the end of the'upright .10.The purpose of these rollers is'to support the carriagebetween theuprights without undue play and at the same time permit the'carriagetobe easily J raised and. lowered.

Brackets 27 may be secured within'the channels of the uprights 10 forthepurpose of limiting the upward movement of the car-' 'riage and soprevent the chainfrom jumping from the sprocket wheel 16 when thecarriage rises. Y

A. sprocket chain preferably of Y formation,has its arms 28 connected tothe lower bar 17 of the carriage and the portion 29 passed over thesprocket wheel 16 with its end connected to a counter weight 30. Thecounter weight 30 may be of any suitable substance but is convenientlymade of concrete which may be chipped ofl" to reduce the weight or addedto'when it is desired to increase. the weight. I V

Means are provided for raising and lowering the carriage, consisting ofa treadle box 31 in which is provided a fulcrum block 32 on which isfulcrumed a lever 33. Connected to one arm of the lever 33 is a footplunger and to the other end of the arm a push rod 35, while to the samearm and between the push rod and, the fulcrum of the lever is connectedat second push rod 36 formed with a forked upper end 37 adapted toreceive and form a rest for the lower bar 17 of the carriage when thecarriage is in lowered position. The frame may' have attached theretothe usual supporting bar 38 held by a brace 39 inwhich bar are journaledrods -"l0 carrying at their upper ends the signals l1.

In practice the invention is operated in the following manner. 7

To lower the carriage the attendant steps upon the foot plunger 34-,forcing the same downwardly, thereby locking the lever and forcing thepush rod 35 upwardly. As the push rod 35 rises it elevates the counterweight 30 a sufficient distance to permit the Weight of the carriage andthe chain to overbalance the counter weight and the carriage descends,the lower bar of the carriage coming to rest in the fork of thepush rod'36.

V17 hen it is desired to again raise the carriage the attendant oncemore steps on'the foot plunger 34, forcing the push rod36 upwardly andelevating the carriage a suiticient distance to permitnthe weight .ofthe chain and the counter weight-30 to over- ,balance the carriage whichwill cause the counterweight to descend drawing the carriage to itsupper position. 7

Having thus described my invention what Iclaim asincw and desire tosecureby Letters Patentfis: i

1'. A target frame, including channel iron 1 u ri hts a rod brid in thesoace between carriage and engageable with the webs of I the uprights,stirrups on the carriage to receive the standards of a target, stopssecured I to the uprights for; limiting the upward movement of thecarriage, -a counter weight,

a sprocket chain passing over the wheel and connected to the carriageand the counter welght, a treadle box, a lever fulcrumed 1n the tread lebox, a foot plunger connected to one end of the lever for rockingthesame upon its fulcrum, a push rod connected to the other end of thelever and adapted to engage the lower face of the counter weight toraise the counter weight when the foot plunger is depressed and a secondpush rod connectedv to the lever between the fulcrum and the first pushrod, having a formed upper end to receive and straddle the lower bar ofthe carriage'when the/carriage descends.

2. A target frame, including channel, iron uprights, a rod carriedbyptheuprights and bridging the space between the uprights, a sprocketwheel mounted for rotation on the rod, a carriage mounted for verticalreciprocation between the uprights, stops for lim- 7 for operating thelever to, alternately thrust the 7 counter weight and the carriageupwardly. I

3. The combination with. atarget frame, including a reciprocablecarriage,- of' a treadle box, a lever fulcrumed in said'box,
